In the figure: 1 hub, 2 thermocouples, 3 stop pins, 4 rotating shafts, 5 electric heating elements, 6 first magnets, 7 springs, 8 second magnets, 9 delivery pipes, 10 filter screens, 11 magnet exciting coils and 12 cavities.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
Referring to fig. 1-2, a new energy automobile tire comprises a rotating shaft 4 installed on the center of a tire crown, a hub 1 is fixedly connected to one end of the rotating shaft 4, the area of the hub 1 is larger than that of the tire crown, four thermocouples 2 arranged in an annular shape are arranged on the hub 1, a plurality of cavities 12 arranged in an annular shape with the rotating shaft 4 as the center are arranged on the hub 1 at equal intervals, a second magnet 8 is fixedly connected to the side wall of the cavity 12 close to the rotating shaft 4, an excitation coil 11 is wound on the second magnet 8, a stop pin 3 is connected in the cavity 12 in a sliding manner, a first magnet 6 is fixedly connected to one end of the stop pin 3 close to the second magnet 8, a spring 7 is fixedly connected to one side of the second magnet 8, one end of the spring 7, which is far away from the second magnet 8, penetrates through the first magnet 6 and is fixedly connected to one side of the, conveyer pipe 9 is close to atmospheric one end fixedly connected with filter screen 10, can avoid getting into some solid particles in the pipeline, the condition that leads to the pipeline jam appears, the one end intercommunication atmosphere of conveyer pipe 9, stop pin 3 deviates from the toper setting that is of the one end of first magnetite 6, reduce lifting surface area like this, increase pressure, make stop pin 3 get into in the ice sheet more easily, electric heating element 5 is installed to the one end that stop pin 3 deviates from first magnetite 6, thermoelectric couple 2 respectively with excitation coil 11 and electric heating element 5 electric connection, electric heating element 5 is the annular and coils the setting in stop pin 3, can increase the heating surface area, second magnetite 8 is the same with the relative one side magnetization direction of first magnetite 6, the magnetic field direction and the second magnetite 8 of excitation coil 11 production, the magnetic field direction that produces between the first magnetite 6 is the same.
In the invention, when the ground is frozen, the external temperature is lower, the temperature inside the automobile is higher, so when the automobile runs on the ice surface, because the inside and the outside of the automobile have larger temperature difference, the thermocouple 2 generates current, a part of the generated current flows into the excitation coil 11, a part of the generated current flows into the electric heating element 5, after the excitation coil 11 is electrified, a magnetic field is generated, the direction of the magnetic field is the same as the direction of the magnetic field between the second magnet 8 and the first magnet 6, the repulsive force to the first magnet 6 is increased, so that the pressure between the conical end of the stop pin 3 and the ice layer is increased, meanwhile, the current entering the electric heating element 5 generates heat, so that the temperature of the conical end of the stop pin 3 is increased, the heat can enable the tip of the stop pin 3 to more easily enter the ice layer when the tip of the stop pin 3 touches the ice layer, and when the stop pin, forces from all aspects of the ice layer are arranged around the stop pin 3, so that the skidding degree of the tire is reduced, the braking distance is reduced, and the traffic accidents are reduced.
When under the non-low temperature state, in the continuous rotation process of tire, spring 7 compresses when tire and ground contact, stop pin 3 gets into in cavity 12, when the tread at stop pin 3 place is not with ground contact, stop pin 3 can reset under spring 7's effect, spring 7 plays certain cushioning effect on the one hand, spring 7 makes stop pin 3 do the round trip movement on the one hand, thereby make the inside air of cavity 12 constantly circulate with the external world, thereby make the inside air of cavity 12 flow out from conveyer pipe 12, blow to ground, can blow away the subaerial water in tire the place ahead fast or weather, make the coefficient of friction increase of ground and wheel, thereby make the braking capacity of car strengthen, effectively reduce the braking distance on wet and slippery road surface.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
